3M(TM) All Weather Flashing Tape 8067 is a self-adhered, waterproof flashing membrane designed for sealing around openings and penetrations in exterior walls. This product has a unique acrylic pressure sensitive adhesive that aggressively sticks and stays stuck both at lower and higher application temperatures than traditional flashing tapes. It even adheres to damp surfaces.

Bonds to Most Common Building Materials without Primers and Staples3M(TM) All Weather Flashing Tape 8067 is engineered to increase productivity while solving the most critical flashing problems. Unique acrylic pressure sensitive adhesive sticks and stays stuck to seal around windows, doors and other openings. To prevent moisture intrusion, the thin backing construction effectively conforms and seals around nails and staples with less buildup under siding. Proprietary construction will not liquefy, bleed, or melt in contact with many building sealants or in extreme summer temperatures.

Stays Stuck, Even in Extreme Temperatures. 3M(TM) All Weather Flashing Tape 8067 resists UV exposure for up to 12 months. It can be applied to materials without primers or staples and bonds in surface temperatures from 0° to 176°F (-18° to 80°C) per AMAA 711-05. Its proprietary backing seals around nails and staples to prevent moisture intrusion. This backing is also tough, resists punctures and tears, yet it is thin to fit conveniently into corners and under siding. The split paper release liner provides fast application with easy and accurate positioning of the tape.
